get_account

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It reveals the authentication requirement (SPOTIFY_SP_DC) but does not disclose other behavioral traits such as read-only nature, rate limits, or error responses. The disclosure is partial but helpful.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, front-loaded sentence. Every word is essential, no filler. It efficiently conveys purpose and a key requirement.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return value details are covered. The description provides core purpose and auth info but could improve by noting what 'product state' means or typical use cases. Still, it's largely complete for a simple parameterless tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

There are zero parameters, and schema coverage is 100%, so the baseline of 3 applies. No additional parameter semantics are needed as the tool requires no input.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool fetches the 'logged-in account's product state', specifying a unique resource distinct from siblings like get_track or get_playlist. The verb 'Fetch' and resource 'account product state' are specific and unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes a crucial prerequisite: 'needs SPOTIFY_SP_DC', guiding the agent on required credentials. While it doesn't explicitly list when to use alternatives, the context implies this is for account-level data, distinct from other get tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
